The Ultimate Guide to Custom ROMs for the Huawei P40 Pro: Breaking Free from HMS

The Huawei P40 Pro is a masterpiece of hardware—a stunning curved OLED display, a class-leading camera system (including the periscope 5x zoom), and a sleek, premium build. However, its Achilles' heel has always been software. Due to US sanctions, the P40 Pro ships without Google Mobile Services (GMS), relying instead on Huawei Mobile Services (HMS) and the AppGallery.

For many users, this is a deal-breaker. But for the tinkerers, the developers, and the privacy-conscious, the solution lies in custom ROMs—replacing Huawei’s EMUI with a different operating system.

This guide provides a complete, realistic picture of the custom ROM landscape for the P40 Pro (codenamed ELS-NX9 or ELS-AN00).

The Verdict:

If you bought a P40 Pro cheap second-hand and you hate HMS with a passion, do not install an AOSP GSI. The camera loss is too severe. Instead, pay for the bootloader unlock and install a stock-based custom ROM like EliteROM or simply use the Googlefier exploit without unlocking. Custom Rom For Huawei P40 Pro

For 95% of users, the Googlefier method (no unlock) is the correct answer. It gives you 90% of Google functionality with 100% of the camera quality.

2. EliteROM (Based on EMUI)

EliteROM is one of the few names in the Huawei custom scene. It takes stock EMUI 11 or 12, debloats it, integrates Magisk (root) pre-installed, and patches the kernel to allow GMS to run as system apps.

  • Requirements: Unlocked bootloader.
  • Features: Full Google Play certification, advanced power menu, call recording, and Viper4Android support.
  • Downsides: Based on old security patches. No OTA updates.

The Future Outlook

With Huawei shifting entirely to HarmonyOS NEXT (which drops Android compatibility entirely), the chance of future custom ROMs for the P40 Pro is zero. The current GSI builds are maintained by only two developers on XDA (recognize users phhusson and AndyYan). When they stop, the P40 Pro custom ROM scene dies.

Introduction: The Huawei P40 Pro Paradox

The Huawei P40 Pro remains, to this day, one of the most exquisitely engineered smartphones ever made. Its Leica quad-camera system, the "Overflow Display" with 90Hz refresh rate, and the Kirin 990 5G chipset were flagship killers in every sense. However, the device shipped with a catastrophic Achilles' heel: No Google Mobile Services (GMS).

Due to US sanctions, Huawei launched the P40 Pro with its own Huawei Mobile Services (HMS) and the AppGallery. For millions of users worldwide, this was a dealbreaker. The inability to use Google Pay, YouTube, Gmail, or the Play Store natively forced many to look for drastic solutions. Enter the world of Custom ROMs.

Installing a custom ROM on the Huawei P40 Pro is not a journey for the faint of heart. It is a technical odyssey filled with bootloader locks, paid services, and significant risks. But for those willing to tinker, the reward is a fully functional Google-integrated flagship phone. This article explores everything you need to know. The Verdict: If you bought a P40 Pro

The Elephant in the Room: The Kirin Bootloader Lock

Before we list a single ROM, we must address the hardware reality. Unlike Snapdragon-powered phones (like Xiaomi or OnePlus), Huawei’s Kirin chipsets come with a permanently locked bootloader on most global models.

A custom ROM requires an unlocked bootloader. Without it, you cannot flash TWRP or the ROM itself.

  • The Bad News: Huawei officially stopped providing bootloader unlock codes in 2018. You cannot legally or easily unlock the bootloader on a standard P40 Pro (ELS-NX9).
  • The Workaround: Some third-party services (HCU Client, DC-Unlocker, or paid "unlock" sellers) claim to bootloader unlock the P40 Pro via test-points or leaked engineering software. Warning: This often costs $50-$100, voids your warranty immediately, and carries malware risks.

Verdict: You cannot install a custom ROM on a locked P40 Pro. If you haven't unlocked your bootloader already, you are likely stuck with EMUI/HarmonyOS.

Known Issues / Bugs

Custom ROMs on Huawei devices are community-driven and may have imperfections. Common issues on P40 Pro ROMs include:

  • Camera Quality: Stock Huawei camera processing (Leica algorithms) may be lost. You will rely on GCam ports or standard camera apps, which may not utilize the periscope zoom lens perfectly.
  • VoLTE/VoWiFi: In some regions, Voice over LTE and Wi-Fi Calling may be difficult to configure.
  • NFC: Some ROMs have intermittent NFC issues for payments.
